ALLEN F. TERRY AND GEORGE I. TERRY, OF ATHENS, ALABAMA.

CULTIVATOR.

Application filed October 13, 1911.

To all whom it may concern:

Be it known that we, ALLEN F. TERRY and Gnonon I. TERRY, citizens of the United States, residing at Athens, in the county of Limestone and State of Alabama, have invented certain new and useful Improvements in Cultivators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in cultivators, and is designed to constructa device of this nature wherein the same may be adjustable to various widths of rows and heights of operators.

It has been heretofore found that in the ordinary or standard type of manual guided cultivators, that there has been no means of adjustment whereby the handles thereof may be raised or lowered to conform with the height of the operator.

It is the object of the present invention to overcome this objectionable feature, by pro viding a means whereby said handles may be raised or lowered to conform with the height of the operator, thereby increasing the accuracy and comfort with which the machine may be operated.

A further object of the present invention is to provide a cultivator which may be adaptable to the various widths of rows, in order to eliminate the necessity of operating upon the same row twice, which has been customary in widely separated rows.

With the above and other objects in view, this invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated, wherein Figure 1 is a side elevation of a cultivator constructed in accordance with the present invention; Fig. 2 is a top plan view thereof; Fig. 3 is a perspective view of the bar pro viding the adjusting means for the cultiva tor bar; and Fig. 1 is a front elevation of the cultivator tooth, illustrating the manner in which the same is attached to the cultivator beam.

The cultivator forming the subject matter of the present invention comprises a pair of divergent cultivator beams hinged adjacent to the clevis through the instrumentality of which a swingle tree may be secured to the Specification of Letters Patent.

cultivator, having their rear terminals bent downwardly and cultivator teeth secured thereto in a manner which will hereinafter be more fully described. A rod extending through the extreme forward terminals of the converging cultivator beams has pivoted thereto for movement in vertical plane a single cultivator beam, which likewise has its rear terminal bent downwardly, and a cultivator tooth secured thereto. Adjusting meansis interposed between the hinged portions of the divergent cultivatorbeams, and is of such construction that the divergency thereof may be regulated as well as the position of the central cultivator beam. The bolt securing this mechanism through the divergent cultivator beams likewise pivotally secures the handle to said divergent cultivator beams, said handles being adjustable in a vertical plane, as will hereinafter be more fully set forth and described.

Reference being had more particularly to the drawings, 10 indicates divergent cultivator bcamsconstructed of angle irons and providedwith the hinged portions 10 the rear terminals of said hinged portions being curved downwardly, and provided with the cultivator teeth and attaching means, which will hereinafter be more fully described. The forward terminals of the converging arms 10 meet in the clevis 11 to which swingle trees may be secured, and are likewise secured and pressed together by the bolt 12 piercing the same, to which is pivotally connected the central cultivator beam 13. This beam extends rearwardly between the divergent beams 10 and is likewise curved downwardly at its rear terminal, where is provided a cultivator tooth, the attaching means of which is similar to the cultivator teeth of the divergent arms, 10*. The downwardly bent terminals of the divergent beams 10 and the central beam 13 are provided with the horizontal arms 14, which are pierced by the registering openings 15. A pair of vertical arms 16 extend below each side of the horizontal arms 14: and provide a pivotal point for the shank 17 and the cultivator teeth 18. The upper terminals of the shank 17 operate between the arms 14L and are retained at various angles to the pivotal point thereof by the bolt piercing said shank and the openings of said arms 14. From this construction it will readily be seen that the cultivator teeth pivotal sections of the beams 10, and

have the base portions thereof pierced ,by

' the openings 20, said sockets adapted to receive the bar 21 which is interposed between the; divergent arms and is pierced by the'adjusting openings 22, any one of which central; cultivator beam 13 is secured to the is adapted to. register with the opening 20,

it so; desired, and beheld in this position by the; bolt. which is adapted; to pass through said: registering, coinciding opening. The

' bar 21in any suitable manner, preferably by having a bar pass through said cultibeam in such a manner that there is suificient play in, Said: connections for the free. movement of the. central cultivator beam 13-.- The sockets-19 are provided with thez 'upwardly" bent; portions 23 which are pierced by the bolts 24 tosecure the sockets to; the divergent hinged portion of the beams 10. These boltsform: a pivotal connectiong between" thel handles 25 and the divergent pivotal sections 1.0%: of the cultivator beams. 10.:

In order to: provide: a means whereby the heighflof: the1hand-les251 may be adjusted, a

-support.26:is rigidly secured to. the rear terminals; of each; of the divergent. hinged sectionslO, and? are piercedat their upper terminalsbythe bolts 27 The handles125 opferate in the. interior of' these rods and are gm cla ms must ay be sinci s:

adapted; to; be retained invarious positions thereof by the bolts 28 piercing said arms and said rods. The width of thecultivator 'handles25 is regulated by the telescopic rod plow carrying beams having spaced tongues formed upon their forward ends for receiving said first named tongues therebetween, bolts. pivotally connecting said tongues to permit of the lateral swinging movement of the beams, said tongues preventing independent oscillatory movement of said beams with respect to the hitch, angle plates secured to the inner sides of said beams and having horizontal portions extending from one beam toward the other, the edges of said horizontal portions being bent to form guiding grooves, a cross bar having its end seated in said guiding grooves and provided with spaced openings, said horizontal portions being provided with spaced openings, adapted for alinement with the spaced openings in the ends of said cross bar for adjustably connecting the cross bar to the angle plate.

In testimony whereof we aifix our signatures in presence of two witnesses.
